INDICATED USE: General
purpose survey with alarm capabilitiesDETECTOR: 6”(15.2cm) diameter X 1”(2.5cm) thick plastic scintillation
detectorSENSITIVITY: Typically 2000 cpm/µR/hr (137Cs
gamma)METER DIAL: 0 - 1 µR/hr, BAT TEST (others available )MULTIPLIERS: X1, X10, X100, X1000LINEARITY: Reading within ±10% of true valueALARM: The Model 193 has a dual action alarm.
1. A fixed alarm point can be set at any point from 10% of full scale
to full scale, and is indicated by a constant audible tone, and the
lamp turning on.
2. A quick deviation alarm that is based on background radiation
levels. When the instrument is turned on, it takes an 8 second
measurement of background radiation levels and determines a
deviation alarm setting. If the radiation level exceeds this
setting, the alarm audio will beep every 1/8 second, and the lamp
will flash.AUDIO: Built in unimorph speaker with ON/OFF switch (greater than 60
dB at 2 feet )CALIBRATION CONTROLS: Accessible from front of instrument (protective
cover provided)RESPONSE: Toggle switch for FAST (4 seconds) or SLOW (22 seconds)
from 10% to 90% of final readingRESET: Pushbutton to zero the meter, and also re-accumulate
background data and recalculate the alarm point.POWER: 2 each “D” cell batteries (housed in sealed compartment that
is externally accessible )BATTERY LIFE: Typically 600 hours with alkaline batteries (battery
condition can be checked on meter)METER: 2.5" (6.4cm) arc, 1 mA analog typeCONSTRUCTION: Cast and drawn aluminum with beige polyurethane enamel
paintTEMPERATURE RANGE: -20°F(-29°C) to 140°F(60°C)OVERALL LENGTH: 51"(129.5 cm)WEIGHT: 8.5 lbs(3.9 kg) including batteries
